n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4

The formula for the synthesis of ammonia from diatomic nitrogen and hydrogen is: N2+3H2-->2NH3
n2 = 20 + n so n2 - n - 20 = 0 that is (n - 5)(n + 4) = 0 so that n - 5 = 0 or n + 4 = 0 n = 5 or n = -4
The balanced equation for magnesium chloride (MgCl2) plus sulfuric acid (H2SO4) is: MgCl2 + H2SO4 → MgSO4 + 2HCl.

Reaction D would result in decreased entropy, as the solid reactant (MgCl2) is breaking into ions in solution, which typically decreases entropy. The other reactions involve gases as reactants or products, which generally increase entropy due to higher degrees of freedom in gaseous states.

1 mole of MgCl2 requires 2 moles of KOH to react based on the balanced chemical equation provided.
The reaction of MgCl2 with Li2CO3 yields 2LiCl + MgCO3. The reaction of MgCO3 with 2LiCl forms MgCl2 + 2Li2CO3.
mg + CuCl2 + MgCl2 + Cu Mg + Cu^+2 = Mg^+2 + Cu
